No reads on opponent, this an old hand where I wasn't using HUD

Thanks for the words. I called and Villain had a flush. Poo on me.

Can you explain why you bet that small on the flop?

I bet I can. You have top 2 and want a caller and a big pot. Most times when you get a caller it will be a flush draw. If you had AQ here I bet you wouldve bet more. Common mistake.
